you can load the variables from the env file via Makefile, see here for example. We don't really have a use case for writing the env variables to an env file, so you can remove this library.

I think if you just do s = session{} it will be better. This way you don't have to worry about clearing all the properties from the session object when you want to log out

I'm a bit confused, did we move the config file to the env file? I am not a big fan of introducing a third party library for a trivial task like writing to a file, so if we decide this is the direction we want to take, we can easily implement this functionality ourselves.
Or we can have a hybrid solution where the broker metadata is stored in a flat file on disk and only the credentials are preserved in the env variable.
@DuarteMartinho what do you think?

the isSecureKafka flag should be changed to isSaslPlaintext, because there are many ways to secure a kafka cluster
